WEEK 1 DQ#1 Thread

Java is a portable language, and being an object-oriented programming language, it also encourages component reusability. How does Java achieve these two important features? How are these features desirable in modern software engineering?

WEEK 1 DQ#2 Thread

You are a bank manager and you are helping a new bank teller understand the kind of accounts the bank offers. If a customer comes in asking to open a new savings account, the teller needs to ask what kind of account passbook savings or certificate of deposit the customer would like to open. Remind the customer that all accounts with our bank are insured by the FDIC. You should explain that all accounts earn some interest; a savings accounts interest is compounded monthly. You should assign a unique account number after accepting the customers initial deposit. If the customer chooses to receive statements electronically, the system will send an e-mail with a monthly statement; if the customer chooses not to, then a paper statement will be sent by mail quarterly.

If savings account is a class, give an example of each of the following as it relates to that savings account. Explain your reasoning behind your example.

PRG/420 Week 2

Simple Commission Calculation Program Part 1 TUTORIAL NOTES FOR RUNNING CODE: Are you using Netbeans? Please confirm that JavaDB server is running. You can check this by going to the Services tab-> Databases -> Java DB -> Right click -> Start server

Write a Java application using NetBeans Integrated Development Environment (IDE) that calculates the total annual compensation of a salesperson. Consider the following factors:

A salesperson will earn a fixed salary of $51,000. A salesperson will also receive a commission as a sales incentive. Commission is a

percentage of the salespersons annual sales. The current commission is 13% of total sales. The total annual compensation is the fixed salary plus the commission earned.

The Java application should meet these technical requirements:

The application should have at least one class, in addition to the applications controlling class (a controlling class is where the main function resides).

There should be proper documentation in the source code. The application should ask the user to enter annual sales, and it should display the total

annual compensation. Submit your assignment using the Programming Assignment Sheet.

Remember to include a UML Class Diagram and some information regarding the design of your program.

Copy and Paste your code text into the Source Programs section and a screen shot of the results in the Output section.

Describe how you tested the application in the testing section. Remember that your program must follow the coding conventions found in the Java Coding Conventions document.

WEEK 2 DQ #1 Thread

What are the three types of errors that you can encounter in a Java program? Describe them, and explain how you would minimize the errors. What are some examples of errors that you have seen before?

WEEK 2 DQ #2 Thread

A class is a blueprint for an object. A class may have a default constructor, a constructor with arguments, accessor methods, mutator methods, public fields, and private fields. Choose a category (such as animal, vehicle, and so on) and describe how you would design a class for it.

PRG/420 Week 3

Simple Commission Calculation Program Part 2 TUTORIAL NOTES FOR RUNNING CODE: Are you using netbeans? Please confirm that JavaDB server is running. You can check this by going to the Services tab-> Databases -> Java DB -> Right click -> Start server

Modify the Week Two Java application using Java NetBeans IDE to meet these additional and changed business requirements:

The company has recently changed its total annual compensation policy to improve sales.

http://uop-tutorials.info/prg420.htmlhttp://uop-tutorials.info/prg420.htmlhttp://uop-tutorials.info/prg420.htmlhttp://uop-tutorials.info/prg420.htmlhttp://uop-tutorials.info/prg420.htmlhttp://uop-tutorials.info/prg420.htmlhttps://www.e-junkie.com/ecom/gb.php?c=cart&i=1411558&cl=286758&ejc=2

A salesperson will continue to earn a fixed salary of $51,000. The current sales target for every salesperson is $120,000

The sales incentive will only start when 80% of the sales target is met. The current commission is 13% of total sales.

If a salesperson exceeds the sales target, the commission will increase based on an acceleration factor. The acceleration factor is 1.25.

The application should ask the user to enter annual sales, and it should display the total annual compensation.

The application should also display a table of potential total annual compensation that the salesperson could have earned, in $5000 increments above the salespersons annual sales, until it reaches 50% above the salespersons annual sales.

Sample Table: Assuming a total annual sales of $100,000, the table would look like this:

Total Sales Total Compensation

100,000

105,000

110,000

115,000

120,000

125,000

130,000

135,000

140,000

145,000

150,000

The Java application should also meet these technical requirements:

The application should have at least one class, in addition to the applications controlling class.

The source code must demonstrate the use of conditional and looping structures.

There should be proper documentation in the source code.

Submit your assignment using the Programming Assignment Sheet

Remember to include a UML Class Diagram and some information regarding the design of your program.

Copy and Paste your code text into the Source Programs section and a screen shot of the results in the Output section.

Describe how you tested the application in the testing section.

Remember that your program must follow the coding conventions found in the Java Coding Conventions document.

TUTORIAL NOTES FOR RUNNING CODE: Are you using netbeans? Please confirm that JavaDB server is running. You can check this by going to the Services tab-> Databases -> Java DB -> Right click -> Start server

A customer has come to your team and has requested a simple application that will allow the customer to store client names, addresses, and telephone numbers. Your team is tasked with building this "database" application. Here are some of the requirements:

In this simple example, the application can programmatically enter data (within the program itself rather than using keyed input).

A constant can be used to set the maximum number of records. The database must check to ensure that telephone numbers are numbers and output a

message if they aren't The database must be able to retrieve client information and display it on the screen for a

specific telephone number match. The program must be well commented and documented using javadoc. The program must conform to the Java Code Conventions

The program must be well labeled, well documented, fully tested, cannot crash, and meet the above customer requirements.
